MYSQL Query for last twelve months of records

Hi I am trying to run a MYSQL query to display all records within a 12 month period. I have to use from_unixtime function to great a date object.

Code:
select call_start_time from call_detail_records
 where call_start_time IN (
   select from_unixtime(call_start_time) from call_detail_records
    where from_unixtime(call_start_time) < Now()
    and from_unixtime(call_start_time) < DATE_ADD(Now(),INTERVAL- 12 MONTH)
   );

The query is syntactically correct but mysql returns no records when there are some. Can someone help?

MSSQL_FETCH_ARRAY(3)													      MSSQL_FETCH_ARRAY(3)

mssql_fetch_array - Fetch a result row as an associative array, a numeric array, or both

SYNOPSIS
array mssql_fetch_array (resource $result, [int $result_type = MSSQL_BOTH]) DESCRIPTION
mssql_fetch_array(3) is an extended version of mssql_fetch_row(3). In addition to storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names as keys. An important thing to note is that using mssql_fetch_array(3) is NOT significantly slower than using mssql_fetch_row(3), while it provides a significant added value. PARAMETERS
o $result - The result resource that is being evaluated. This result comes from a call to mssql_query(3). o $result_type - The type of array that is to be fetched. It's a constant and can take the following values: MSSQL_ASSOC, MSSQL_NUM, and MSSQL_BOTH. RETURN VALUES
Returns an array that corresponds to the fetched row, or FALSE if there are no more rows. EXAMPLES
Example #1 mssql_fetch_array(3) example <?php // Send a select query to MSSQL $query = mssql_query('SELECT [username], [name] FROM [php].[dbo].[userlist]'); // Check if there were any records if (!mssql_num_rows($query)) { echo 'No records found'; } else { // The following is equal to the code below: // // while ($row = mssql_fetch_row($query)) { while ($row = mssql_fetch_array($query, MSSQL_NUM)) { // ... } } // Free the query result mssql_free_result($query); ?> NOTES
Note Field names returned by this function are case-sensitive. Note This function sets NULL fields to the PHP NULL value. SEE ALSO
mssql_fetch_row(3). PHP Documentation Group MSSQL_FETCH_ARRAY(3)
